Abstract
The present invention relates to the fire retardant of one kind structure containing melamine, preparation method and applications, chemical structural formula is:Wherein, substituent R1、R2And R3For any one in hydrogen, tertiary butyl, normal-butyl, cyclohexylalkyl or chloride, bromine, methyl, methoxyl group, nitro, amino, hydroxyl substituted aryl or heteroaryl.Synthetic method is that the Ugi occurred under the concerted catalysis of the copper complex, MIL 101 and the p-methyl benzenesulfonic acid that are loaded with carboxylic acid compound and melamine, aldehyde compound and different nitrile compounds in MCM 41 at 50 DEG C in the in the mixed solvent of methanol and isopropanol reacts, and product must contain the fire retardant of melamine by filtering, extraction and column chromatography.The invention describes that a kind of reaction is simple, by-product is few, the preferable novel preparation method of selectivity is used for selectively production of melamine based flame retardant.The fire retardant thermostabilization of the present invention is good, and fire-retardant rate is high, and up to 97.2%, used raw material is easy to get purity, technique is advanced, is easy to industrialized production.
Description
Technical field
The present invention relates to the fire retardant of one kind structure containing melamine, preparation method and applications researchs.
Background technology
There are secondary hazards such as thickness, the releasings of toxic or corrosive gas when traditional halogen fire proofing burns, to people
Body constitutes safely serious threat, therefore finds new halogen-free flame retardants and be particularly important.Melamine based flame retardant because
With Halogen low toxicity;Decomposition temperature is high, is suitble to processing;Mechanical performance is influenced small;It does not ooze out, does not corrode mold;Flame retardant property
The characteristics such as excellent, the new and effective fire retardant of the structure containing melamine have very big Development volue, cause people widely studied.
In Britain, the ground such as Europe and North America, melamine analog derivative be used to improve polyurethane foamed plastics flame retardant property, and oneself expands
It opens up in other kinds of polymer, such as hard poly- cruel foamed plastics of ammonia, thermoplastic.The application test model of nearest melamine
It encloses and is expanded to nylon and the fields such as pvc pipe.Melamine can be as the reason for excellent flame retardant three when 250~450
Poly cyanamid absorbs heat, reaction of decomposing, and releases ammonia, forms condensation polymer;The melting behavior of basis material is influenced, and accelerates its charcoal
